Hi Guys, I’m completly new with ESP32 programming and actually going through LVGL book by Rui and Sara – practical excercises. Starting first labs I noticed that background color that should be white on your samples is balack in my case and black fonts from your samples are white in my case. Is this something I can manage on my side or this is just bahavior of my CYD (got one from AliExpress). Thanks in advance for your answer.

Hi.

You probably have a board that has two USB ports?
If that’s the case, it’s a little different than the one we use and requires a few changes in the User_setup.h file.

You may need to edit it to uncomment the following lines:

#define ST7789_DRIVER
#define TFT_RGB_ORDER TFT_BGR
#define TFT_INVERSION_OFF

Then, solve the file and compile and upload again to see the result.

Let me know if this solves the issue.

Regards,
Sara

Hi Sara, many thanks for yout tip, it resolved my issue. I’ve got my CYD before I’ve got your book, otherwise I would follow your recomendations on getting the right one 🙂
